Thank you so much for your prompt reply and running the test. I have followed your suggestion and submitted a calculation with only two CPU cores and the "-nk 2" option. Unfortunately, the result was exactly the same. It appears the issue is on our end.</div>

We will request the installation of the latest QE version on our HPC and run tests with it. Hopefully that will fix the issue. </div>

It may or may not be related: if you have 2 GPUs, you should run 2 MPI<br>
processes, preferably with k-point parallelization. Something like:<br>
mpirun -np 2 pw.x -nk 2 ...<br>
